The bung is formed of an outer shell or wall A, made of any suitablemetal or materi al. This shell or wall has on its exterior in theoonstruotion shown a screw-thread, 55T wnelr the bung in its completedcone tion ean be screw-threaded into the head or other portion of thepackage or Can be screwtl'rrez'z-rled into metallic bushing in theheador other portion of the package but in place of having a screw-thread onthe exterior of the shell or wall such exterior can be left smooth andthe bung as a whole driven or otherwise forced into place. The shell orYwall has an interior .chamber A', which is open-at the top and iselosedat the bottom log: fx/'all el, having therein a hole e? for thepassage of the closing-plug or stopper and' raft-tube, and the wall (L2is out away arelmd the hole f3, so as to form a shoulder al and furnishan annular recess or depression lio receive the lower packing-ring orgasket in the Construction shown.

The interior face of the shell or wall A has a so er f--tlrread aextending from the upper end downwardly. The chamber A has enter-fltllereinto a follower B, having a peripheral thread l; to engage thethread a for advanerlg and withdrawing the follower, and the under faceof the follower B abuts against the upper face of a packing-ring orgasket the recess or depression of the shoulder o4, so tlxet with theadvance of the follower the or gesketc, and es the repeeted turning of.

pecking-ring or gasket ywill be compressed. sufficiently to engage thefece of the olosingjplug or stopper and. hol d the plug or stop ernominally in position. The chamber A lios entered thereinto e secondfollower C, the periphery of which hes e screw-threlfl c to engage thescrew-thread' o for adyenc ing' and receding the follower, and the unwder fece of the follower C engages e peck ing-ring or gasket c', restingon the upper ieee of the follower B, so tlmt by edyencing the follower Cthe pecliingd'ing or geelet e will bc tightly compressed around theclos, ing-plug or stopper end eleotuelly seel the bung against theescape of the beer or other liquid and the compressed oir or other pressure-supplying medium, The follower C ie the fictive follower, es the'follower B when once set to compress the pecking b remains set, exceptin cese of weer of the peeking or gasket, when. the follower .B isedyeucedeo es to compress the pecking or gesket end ceuse'the same toagain nominally retein the The cotive follower C is leclvenoed oud.recedecl for, compressing and releasing the peciting-ring the follower@would weer more or less on the end fece of the gasket c in order toprevent such weer e motel washer or e washer of any suitable moteriel c2is inserted between the follower C and the peeking-wing or gasket e",which washer c2 serves to protect the end fece of the peclriugring orgasket iu advancing and receding the follower. The follower B has in itsupper fece notches or recesses bi to receive n, suitable wrench or tool,by which the :follower een be turned into end vout from the chamber A oreen be turned to ect end properly compress the packing-ring or ges het1)/ around the closing-plug or stopper, oud the follower C hes in itsupper fece notcheeI or recesses c3 to coect with e spennenwrench orother tool or instru-ment by which the fol-v lower een be turned intoend out of the chamber A. or een be turned to advance end recede thefollower for compressing and re ceding the pecking-ring or gesket c', esre quired for scaling the bung or for allowing the closing-plug orstopper to be forced or driven out. I

The closing-plug or stopper D een be mede of wood, preferably circularin cross-section, end this plug or stopper is inserted in e.- hole fltherefor, which hole is formed b y e central hole inthe followers,gaskets, and Washer, es shown in Fig. 3.' The lower puoking-ring orgasket b is compressed b the follower B, so that it will nominally hol(the olosingeplug oi' stopper I.) in position, without, however, fullysealing the plug or stopper, es the comn pression must not be so greetes to prevent the plug' or stopper from being readily iorced out byii'isertiug tlpe druft-tube, which tube is entered through the hole (Zfor the plug or eeies stopper. The 'lower paekingering or gasket whenonoe sot romains lo that position.,

The filled package hes the peclringriug or geleitet ctightly compressed eround the closing-plug or stopper, ond for beer andother liquids rcquiring e' stomp such stomp ie to be placed over theouter end ol the bung, es usuel.

It is essentiel in drawing beer that pressureshould be eupplied in order to mehr tein the pressure in the package fordrewiug oil the beer, end the pressure ceu be com0 pressed oir,ceibonic-ecid gos, or other pres sure w `reducing medium.
